I have a problem job where the ME specified some ductless Mr Slim fan coil units to be used for backup cooling for some small archive rooms. The DDC system is to turn on these unit in case the main AHU fails or is otherwise shutdown.
Problem is these unit have remote control thermostats with the on/off button on the remote. Turning them off is easy, just kill power. But, once power is restored, someone must press the on button on the remote control.
Has anyone found a way to turn on these types of units on with a DDC system?
